DECANTING APPARATUS.

Application filed October 19, 1921. Serial No. 508,755.

To all whom it may concern:

Be it known that I, SIGMUND L. GOLD- MAN, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in DecantingApparatus, of which the following is a specification.

My invention relates, more particularly, to decanting apparatusinvolving the use of a member which is positioned in the liquid to bedecanted and containing a passage through which the liquid is withdrawn,by suction action, from the receptacle containing it. I

My primary object is to provided improvements in members of thecharacter referred to, to the end that these members shall operateeffectually to perform their purpose, be simple and economical ofconstruction and readily cleansed of solid matter containedin the liquidand inter- I cepted by the said member in the passage of the liquidtherethrough.

As a premise to the following description it may be stated that certainof my improvements relate to a member of the character stated, whetherthis member be provided as a float member or as a sinker, whereascertain other features thereof relate to the member provided as asinker.

I have therefore shown my improvements as embodied in a member of thesinker type,

' rest, member.

a description of the drawings being'as follows:

Figure 1 is a View in elevation of a sinker member constructed inaccordance with my invention. Figure 2 is a plan view of the lower,rest, portion of the device. Figure 3 is a plan view of a strainermember em at the irregular line .7 on Fig. 2 and viewed in the directionof the arrow.

The particular construction of device shown comprises an upper memberSand a lower member 9 which. are releasably connected together ashereinafter described.

The upper member 8,which is preferably stamped and drawn from a sheet ofmetal,

is hollow and open at its upper and lower ends, its upper end portionbeing preferably in the form of a tubelO and its lower portion of domeshape as represented at 11, the

lower edge of the dome being formed with outwardly-extending lugs12shown as four in number and equidistantly spaced apart, the spaceprovided within the dome 11 being filled with any suitable filteringmaterial, represented at 13, such as sponge. I

The portion lO of the member 8 is provided for attachment thereto ofatube, represented at 14: and which is preferably flexible, it beingdesired that. a rubber tube be employed, through which the suction for]decanting the liquid-would be exerted, as for example by a siphoningaction.

The base member 9 of the device is formed of a section 15 and a weight16. The section 15 is preferably stamped from a-single sheet of metal topresent an upper plateportion 17 and leg portions 18 which extendpreferably at an angle of 90 to the-plate portion 17 at'opposite ends ofthis plate por{ tion. At opposite sides of this plate portion the metalfrom which this member is formed is bent downwardly topresentv de-vpending plate-like portions 19 provided intermediate their ends withdepending lugs 20, the legs 18 and plate portions 19 forming arectangular closure in which the weight. member 16 shown as of squareshape and centrally apertured at 21, extends, the member 16 being heldin place by'bending the lugs 20 into overlapping relation thereto. as 1shown in the drawings.

The metal of the plate-portion 1 7 is cut away to provide the openings22 separated by: the integral strip portions23 of the plate-- portion 17these stripportions being disposed at an angle of to each other, eachspace 22 being in the form of a sector of a circle. The metal of theplate-portionv1j7 adjacent theouter marginal edges of the spaces 22 isdeflected upwardly to form the flanges 24,. corresponding endsof whichare cut away, as represented arena provide spaces between the stripsections 2.3 and the adjacent, ends, of each of the flanges 24, thesespaces being so proportioned as to permit the several lugs 12 on themember 8 to enter them and in such position extend be The device, in theform shown, also comprises a perforated disk 26 adapted tobe locatedbetween the plate portion 17 at the strips 23 of the latter, and thelower edge of the member 8, thereby to form a sieving member, the-disk.2-6 being preferably providedfwit h radially-extending lugs 27equidistant? spaced apart at which this disk is clampe in position uponassembling the partsS and 9 together, as stated.

, It will be understood that in the use of the device, as shown, thedevice upon being introduced into a body of liquid'to be decanted, sinksto the bottom of the receptacle in which the liquid is contained andrests on its legs 18, the member 16 being provided to afford to thedevice sufiicient weight to cause 'it to sink as statedand bear downonthe bottom ofthe receptacle with such firmness thatit cannot bereadilyshifted, thereby to avoid disturbing the sediment in the bottomof the receptacle, it being noted that the bottom of the passage in thedevice extends a considerable distance above the bottom surfaces of thelegs 18, so that the liquid drawn from the receptacle through the deviceand tube .14 is that which is above any accumulations of sediment in thereceptacle. It may be here stated that it is desired that the variousstamped "metal parts of the structure be made fronirelatively thinmetal, and this I is made- ,possible by the provisiono-f the member 16which affords to the device the necessary weight to cause it to sink .inthe liquid and seat with; the desired firmness upon the bottom of thereceptacle. While the device is shown as provided with both a screeningdisk 26 and a "body of filtering material 13, it will be readilyunderstood that, especially where the filtering material 13 is ofsponge,-the disk 26 may be omitted, in which case it would be desirableto provide the flanges 24: of l'essjhe'ight. Furthermore, under someconditions of use, the screening device'26 may be all that it isnecessary'to provide to effect'the desired straining of the liquid.VVh'ere the screening device is omitted the'portions 23 preventdisplacement of the filtering material 13.

It will be noted that 'by providing the device as shown and described itmay be made-almost wholly of sheet metal and very economicallyandmay'beprovided as a very small and compact device, which also makesfor economy inmanufacture. Furthermore, by providing the illustrated anddescribed means for releasably holding the 'two'sections '8 and 9together, the parts maybe readily assembled and disassembled, the lat- Asaid upper section and 'formed of a por tion formed from a sheet ofmaterial and providing depending portions spaced apart, the upperportion of said sheet containing an aperture registering with theinterior of said uppersection and a weight-member connected with saidlower section.
